Frequent formatting of hard disk---good or detrimental?
Of course, the more you use a device with mechanical parts, the quicker it will wear out and start causing problems. However, from a practical standpoint, it really won't make that much difference. On the positive side, by reformatting your hard disk and then reinstalling your operating system and applications, you will be making your overall operating environment more stable and probably faster. As you surf the web, install and uninstall appications, etc., there is a lot of "junk" that accumulates on your system that is not removed by even the best utilities. Re-freshing your environment by a format and re-install, in essence, gives you a fresh start and is a good thing to do periodically, especially if you keep your system for many years like most of us.
